The hardware control panel
When you connect the TTM 57SL to Scratch
LIVE
, the hardware
control panel appears. You can show or hide this panel by clicking
on the
hardware
button.
You can control many of the features of Scratch
LIVE
directly
from your TTM 57SL mixer. The hardware panel shows you
what functions in the software are connected to the physical
controls on the mixer, and allows you to customize the control
assignments. It also provides an interface for the effects running
in the mixer.
Controlling Scratch
LIVE
from the TTM 57SL
Each of the controls on the mixer controls a software function in
Scratch
LIVE
.
Each parameter knob (labeled
P1
and
P2
on the mixer) has
two states. The LED next to P1 and P2 on the mixer indicates the
state: the control
above
applies when the LED is
off
, the control
below
applies when the LED is
on
. Some controls, such as “tap
tempo”, and “load track” are momentary.
The joysticks
J1
and
J2
also have two states. When the LED
next to J1 or J2 is
on
, the joystick controls Scratch
LIVE
software.
When the LED is not lit, the joystick acts as a transform switch.
To switch between using the joystick as a control for Scratch
LIVE
and a transform switch, press the joystick straight down and hold
it down.
Note: the joystick is also a button, press it straight down, as if you
were trying to push it into the mixer – you will feel it click.
When you are in transform mode, the LED next to the
joystick is not lit, and its controls on the Scratch
LIVE
hardware
panel are grayed out.
Groups
Functions are organized in a series of groups. Each group con
-
tains a bank of software controls. The first two groups are custom
groups, designed to contain the commands you need most often
during a set. The next four groups contain other functions or
-
dered by category.
To access a group, press the
GROUP
button on the mixer,
then press:
B1 – general:
Custom group 1, with the most common com
-
mands.
B2 – library:
Custom group 2 — move through library, make
new recordings.
B3 – playback:
Control all playback functions directly from the
mixer.
B4 – cue/loop:
Full control over all cue points on both Virtual
Decks and looping.
B5 – recording:
Select source and start / stop / save / play
recordings.
B6 – effects:
Select and insert effects. Adjust effect parameters.
Customizing the control assignments
You can customize almost all of the software control assignments.
To change what a button, parameter knob or joystick does to
Scratch
LIVE
,
right-click on the control label
. A list appears, and
you can choose the new function you wish to have associated
with that control.
Some software functions can be assigned to either the left
or the right Virtual Deck. If you choose a function that can be
assigned to a Deck, after you select the function from the menu,
you will be presented with another list. Choose
selected deck
to
have the function controlled by the
DECK
button on the mixer,
or
left deck
or
right deck
to have it always apply to one of the
decks.
Any customization resides in the computer, not in the mixer.
This means that if two different DJs, each with their own laptop,
use the same mixer, each DJ can have their own custom groups.
See the
save to mixer
function on page 32.
